Wednesday, 1 March 2023. Harmony Gold Mining Company Limited (Harmony or the Company) is pleased to report our financial and operational results for the six-month period ended 31 December 2022. MESSAGE FROM THE CHIEF EXECUTIVE OFFICER OVERVIEW Our strategy of allocating growth capital towards high-margin, long-life assets has already started to deliver the desired results. Our copper journey has begun in earnest with the conclusion of the Eva Copper acquisition in the tier 1 mining jurisdiction of Australia. This near-term copper project complements our tier 1 Wafi-Golpu copper-gold project in Papua New Guinea. These assets bolster the Harmony investment case as gold-copper specialists with a growing international footprint. Safety remains our number one priority and takes precedence over everything at Harmony. A proactive culture of safety and care continues to be embedded at all levels through our ongoing Thibakotsi humanistic cultural transformation programme. The result of our dedicated and unwavering safety effort is evident in a group LTIFR of 5.38 per million hours worked in the first half of this financial year. Our LTIFR has remained below 6.00 per million hours worked now for five consecutive quarters. Harmony had a successful return to work with no incidents or disruptions after the December 2022 break. This was our second consecutive loss-of-life free January. Further recognition must be awarded to the entire South African mining industry for recording its first ever loss-of-life free January. Although we have a strategy to grow and diversify Harmony, our core business is still predominantly South African gold. I am therefore pleased that our South African assets have performed well on all key performance indicators despite the many challenges facing the industry. Excellent recovered grades at our South African underground operations in the second quarter of this financial year (Q2FY23) ensured we remain on track to meet our full-year production, cost and grade guidance. The energy shortage has forced us to implement plans to mitigate the effects of load curtailment. Our underground mines have excess capacity allowing for the optimisation of various functions including the compressed air network, ventilation and time-of-use such as weekend hoisting. Harmony has an integrated approach to risk management. We are proactively managing the ongoing energy challenges to ensure our people remain safe at all times and with the least possible impact on production. Our South African underground operations' production was largely flat at 17 179kg (552 316oz) in H1FY23 if we adjust the six-month period ended 31 December 2021 (H1FY22) production for the closure of Bambanani at the end of FY22. All the South African underground operations, including Bambanani, returned R1 858 million (US$107 million) in operating free cash flow, up 33% from R1 395 million (US$93 million) in H1FY22. This is a commendable achievement, especially given the challenging South African operating conditions. We obtained approval to begin construction of the Kareerand tailings storage facility (TSF) at Mine Waste Solutions in December 2022 and construction is now underway. Our surface source operations still delivered a positive R160 million (US$9 million) in operating free cash flow after the major capital deployed to extend this TSF. Internationally, waste stripping at Hidden Valley continues as we expose the higher-grade ore at Big Red and Kaveroi. Mining of these high grades will commence in the second half of this financial year. * H1FY22 – six-month period ended 31 December 2021 # LTIFR – lost-time injury frequency rate

 
2 Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2022 Gold revenue for this reporting period increased by 6% to R22 750 million (US$1 314 million) compared to R21 510 million (US$1 431 million) in H1FY22. This increase was mainly as a result of higher underground recovered grades and a 12% increase in the average gold price received to R963 439/kg (US$1 730/oz) from R860 795/kg (US$1 782/oz). The South African underground operations delivered a 5% increase in underground recovered grade of 5.68g/t in H1FY23 from 5.39g/t in H1FY22. Underground recovered grade for the second quarter of FY23 was 6.04g/t. This corresponds with the higher development grades disclosed in our FY22 results. Group production in H1FY23 decreased by 5% to 23 037kg (740 655oz) from 24 226kg (778 879oz) in H1FY22 mainly due to the closure of Bambanani at the end of FY22. Adjusting for this, group production decreased by 2% or 353kg (11 346oz) year on year. Group AISC increased by 11% to R890 735/kg (US$1 600/oz) in H1FY23 from R802 260/kg (US$1 660/oz) in H1FY22. This increase was mainly due to the higher AISC at Target 1, Kusasalethu and Hidden Valley. On a quarterly basis, AISC actually decreased by 4% in Q2FY23 to R873 740/kg (US$1 544/oz) compared to R907 864/kg (US$1 657/oz) in the first quarter of this financial year (Q1FY23). This was mainly driven by the winter electricity tariffs in Q1FY23, improved recovered grades at the South African underground operations and at Mine Waste Solutions. Group operating free cash flows in H1FY23 decreased by 14% to R1 949 million (US$113 million) from R2 272 million (US$151 million) in H1FY22 due to the planned higher capital expenditure. Operating free cash flow was boosted in H1FY23 by good recovered grades and the higher average gold price received. Effective capital allocation is critical as we aim to continue delivering positive total shareholder returns, organic and inorganic growth alongside true sustainability. Group capital expenditure for H1FY23 increased by 15% to R3 630 million (US$210 million) from R3 158 million (US$210 million) in H1FY22 to advance the Zaaiplaats and Kareerand extension projects. Total capital expenditure for FY23 is forecast to be R8 000 million (US$468 million)* compared to the R8 500 million (US$498 million)* guided at the end of FY22 due to the regulatory delay on the Kareerand extension. Group all-in costs for this reporting period increased by 13% to R932 018/kg (US$1 674/oz) from R823 938/kg (US$1 705/oz) in H1FY22. Due to the conclusion of the Eva Copper acquisition on 16 December 2022, net debt increased to R4 710 million (US$277 million) at the end of December 2022 from R757 million (US$47 million) at the end of FY22. The purchase price of US$170 million (R2 996 million) was paid using available debt facilities. Net debt to EBITDA has therefore increased to 0.6 times from 0.1 times in H1FY22, still well within covenant thresholds. Harmony’s dividend policy is to pay a return of 20% of net free cash generated (net free cash is defined as operating free cash flow after capital, interest, tax, corporate and other expenses), to shareholders at the discretion of the board of directors. As Harmony invests in margin expansion, life-of-mine extension and various other growth opportunities, it is prudent to maintain a strong balance sheet and good liquidity. A decision has therefore been taken to not pay an interim dividend for this reporting period. Basic earnings per share increased by 31% to 298 SA cents (17 US cents) compared to 227 SA cents (16 US cents) per share in the previous reporting period. Headline earnings per share increased by 18% to 293 SA cents (17 US cents) per share compared to 248 SA cents (17 US cents) per share in H1FY22. * These amounts were converted using the forecast short-term exchange rate of R17.08. HEALTH AND SAFETY Responsible Stewardship is the first of our four strategic pillars and we are committed to achieving our goal of zero loss-of-life. In addition to safety, the prevention of work-related illness and mental wellbeing, is of critical importance. We continue with our various healthcare initiatives, ensuring a healthy and engaged workforce. It is with deep regret that we report three colleagues lost their lives in mine-related incidents in H1FY23. We pay our respects and send our heartfelt condolences to the families and loved ones of the following colleagues who are no longer with us: Juliao Antonio Macamo (stope team leader, Moab Khotsong), Ernesto Euseblo Macuacua (equipping team leader, Tshepong North) and Bongile Mcuntula (driller, Kusasalethu). For the South African operations, LTIFR improved to 5.65 per million hours worked for H1FY23 compared to 5.99 per million hours worked for H1FY22. The loss of life injury frequency rate improved to 0.07 in H1FY23 compared to 0.14 per million hours worked for H1FY22. Hidden Valley’s LTIFR for the reporting period has increased to 1.03 from 0.00 per million hours worked in H1FY22. Some of the notable safety milestones achieved in H1FY23 included: • fall of ground injury frequency rate in the second quarter improved to 0.78 from 1.17 per million hours worked. This is the best quarterly performance in four years • total South African operations achieved 8 million rail-bound equipment loss-of-life free shifts. ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) AND ENERGY-SAVING INITIATIVES Embedded sustainability has always been integral to how we operate at Harmony. We are therefore proud of the external recognition we continue to receive. Harmony has once again been included in the FTSE4Good Index. For the fifth consecutive year, Harmony has further been included in the Bloomberg Gender-Equality Index. Harmony fosters gender diversity and inclusivity, and treats all our employees fairly without bias or prejudice of any kind. The company also achieved a score of ‘A’ from the CDP for our best practice water management strategy. Harmony has committed to set near-term company-wide emission reductions in line with climate science with the Science Based Target initiative (SBTi). Our near-term and longer-term targets have been validated and approved by SBTi. We have committed to reducing absolute scope 1 and 2 greenhouse gas emissions by 63% by FY36 from a FY21 base year. We are confident of achieving our goal of net zero emissions by 2045. Construction of the first phase of our renewable energy programme to generate 30MW of solar power is currently underway. We anticipate full commissioning of phase 1 by the end of the financial year. Feasibility studies have been completed for the 137MW phase 2 project, with construction expected to commence soon. The first 100MW will be on balance sheet and largely funded using the R1.5 billion (US$88 million)* green loan and is expected to be completed in September 2024. As with phase 1, the remaining 37MW will be delivered by an independent power producer. MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued

 
3 Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2022 Electricity currently represents approximately 18% of group operating costs. In order to reduce the impact of escalating tariffs and drive decarbonisation, we have implemented more than 200 energy-saving initiatives. These initiatives have yielded a cumulative cost-saving of over R1.4 billion since 2016. This translates to a reduction of over 1.5 million tonnes of CO2 equivalent emissions. More information is available in our 2022 ESG and TCFD reports on our website. * This amount was converted using the spot exchange rate of R17.00 at 31 December 2022. OPERATIONAL AND FINANCIAL RESULTS FOR H1FY23 (COMPARED TO H1FY22) Our mines continue contributing positively towards our strategy of safe, profitable ounces and improving margins. To ensure continued positive returns, we directed major capital towards our lower-risk and higher-margin assets and projects. This will ensure a higher return on capital and we are seeing the anticipated results. We have grouped our operations into four business areas, as discussed below. 1. South African underground operations: optimised These operations delivered an improved operating performance in H1FY23 compared to H1FY22. The optimisation programme has resulted in improved profitability and higher operating free cash flow. Production in H1FY23 from these operations was flat year-on-year at 10 548kg (339 125oz) compared to 10 512kg (337 967oz) after adjusting H1FY22 production for the 836kg (26 878oz) contribution from the high-grade Bambanani mine which closed at the end of FY22. Average underground recovered grades at these operations also increased to 4.98g/t in H1FY23 from 4.54g/t in the previous reporting period. AISC for the South African underground optimised operations increased by 8% to R914 454/kg (US$1 642/oz) in H1FY23 from R843 093/kg (US$1 745/oz) in H1FY22. This increase was mainly due to the ongoing project at Target 1 and lower-than-planned underground recovered grades at Kusasalethu. Notably, operating free cash flow margins from Tshepong North and Tshepong South improved to 8% and 18% from -10% and 8% respectively. Joel’s operating free cash flow margin for this reporting period also improved to 12% from -16%. The performance of these mines demonstrates the successful turnaround strategy aimed at improving the margins and operational free cash flow of these assets. The turnaround for Target 1 is still underway with the project expected to be completed before the end of this financial year. There have been some delays, but once the project is complete, we anticipate margins and profitability at Target 1 to improve on the back of higher volumes and lower costs. 2. South African underground operations: high-grade Our high-grade mines, Mponeng and Moab Khotsong, had a good second quarter driven by an increase in tonnes milled and an improvement in underground recovered grades. Production for H1FY23 was largely flat at 6 631kg (213 191oz) compared to 6 613kg (212 612oz) in H1FY22. At Mponeng, underground recovered grades increased by 20% to 8.72g/t in Q2FY23 from 7.29g/t in Q1FY23. This resulted in a 13% increase in gold production at Mponeng in Q2FY23 to 1 839kg (59 125 oz) from 1 634kg (52 534 oz) in Q1FY23. AISC for our high-grade operations increased in line with plan by 7% to R814 011/kg (US$1 462/oz) in H1FY23 from R757 338/kg (US$1 567/oz) in H1FY22. Operating free cash flow from these two mines increased by 7% to R1 043 million (US$60 million) in H1FY23 from R979 million (US$65 million) in H1FY22, mainly due to the improved recovered grades at Mponeng and the higher average gold price received. The Zaaiplaats project at Moab Khotsong is progressing well. Feasibility studies to determine the possibility of deepening Mponeng and conducting pillar extractions at Savuka and Tau-Tona are also underway. We expect to conclude these studies as part of our annual planning cycle in August 2023. 3. South African surface operations H1FY23 production from surface sources decreased by 12% to 3 875kg (124 584oz) from 4 394kg (141 269oz) due to the depletion of the rock dumps and lower recovered grades at Mine Waste Solutions. Production at our surface source operations was also negatively impacted by the cyanide shortage during the second quarter of FY23. This has now been resolved. Quarterly production from our surface sources however, improved by 2% to 1 958kg (62 950oz) in Q2FY23 compared to 1 917kg (61 634oz) in Q1FY23. The improvement in the second quarter was driven predominantly by a 6% improvement in recovered grades to 0.18g/t from 0.17g/t in Q1FY23. South African surface operations' AISC for H1FY23 increased by 25% to R800 410/kg (US$1 437/oz) compared to R639 027/kg (US$1 323/oz) in the previous reporting period. This was mainly due to above inflation increases in prices, specifically reagents. Sequentially, AISC for our surface source operations improved by 8% to R767 259/kg (US$1 356/oz) in Q2FY23 from R835 803/kg (US$1 526/oz) in Q1FY23. This was mainly as a result of the higher recovered grades and lower electricity costs due to the winter tariffs in Q1FY23. The surface source business generated operating free cash of R160 million (US$9 million) in H1FY23 compared to R842 million (US$56 million) in the previous reporting period. The 81% decline in operating free cash was a result of major capital deployed at Mine Waste Solutions for the Kareerand tailings extension. 4. International Hidden Valley Gold production in H1FY23 at Hidden Valley increased by 6% to 1 983kg (63 755oz) against the 1 871kg (60 153oz) in the comparable period. Waste stripping continued throughout the first six months of FY23 as we target higher-grade ore. Recovered grade in H1FY23 improved by 2% to 1.00g/t from 0.98g/t in the comparable reporting period. We expect further upside in recovered grade as we access the high-grade areas at Kaveroi and Big Red. Production trends in crushed material transported by the overland conveyor belt continue to improve since we implemented a dedicated improvement programme after the conveyor belt failure in FY22. The prolonged drought in Papua New Guinea has impacted Papua New Guinea Power Limited's hydroelectric power generation and supply. On-site diesel power generation has therefore been necessary albeit at a higher cost. The commissioning of the Baime “run of river” Hydroelectric facility in Bulolo (±40km from site) is due to be completed in H2FY23. Once completed, this will improve the power generation challenges and reduce the on-site diesel power generation requirements. AISC for H1FY23 increased by 10% to R1 204 686/kg (US$2 162/oz) from R1 093 841/kg (US$2 269/oz) due to the increase in diesel costs and the weakening of the Rand against major currencies.

4 Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2022 MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued Wafi-Golpu Project Progress has been made in recent discussions between Harmony, our joint venture partner Newcrest Mining Limited and the Papua New Guinea Government regarding the potential terms of a Mining Development Contract (which is required for a Special Mining Lease). The parties are working to align on a range of fiscal and non-fiscal matters and active engagement continues towards finalising the detailed terms of the Mining Development Contract. Eva Copper Harmony concluded the Eva Copper transaction on 16 December 2022. The purchase price of US$170 million (R2 996 million) was paid using available debt facilities. Updating of the feasibility studies has commenced and we will provide an update during the course of calendar year 2023. The future contingent payment of up to a maximum of US$60 million will only become payable if the necessary criteria are met. This contingent payment consists of up to US$30 million via a 10% sharing of net incremental revenue above US$3.80/lb Cu and up to US$30 million on a new copper resource discovered and declared within the acquired tenements (calculated using a resource multiple of US$0.03/lb Cu). Refer to note 12 for further detail. Eva Copper introduces near-term copper to Harmony’s production profile. It has the potential to add 10 to 15% in gold and gold equivalents and is anticipated to be placed in the lower half of the C1 cash cost* curve over its 15-year life of mine. * This is a standard metric used in copper mining to denote the basic cash costs of running a mining operation. Cost management Cash operating costs increased by 6% (below the planned increase of 8%) to R17 069 million (US$986 million) from R16 178 million (US$1 077 million) in H1FY22. This lower-than-planned increase is attributable to the closure of Bambanani which reduced costs by R612 million (US$41 million) and a year-on-year decrease in fixed labour costs due to a reduction in the number of employees who left Harmony in H1FY23 either voluntarily or for medical reasons. The following resulted in higher cash operating costs during this reporting period: • consumables increased by 22% or R892 million (US$17 million) mainly due to a 113% increase in diesel costs at Hidden Valley compared to H1FY22 • other distributable costs increased by R255 million (US$12 million), 46% higher than H1FY22. This was due mainly to inflationary increases as well as increased rental costs for industrial equipment • external contractor costs increased by R139 million (US$10 million), a 7% increase compared to H1FY22. This was due to a combination of inflation and increases in the cost of rock transport, security costs, as well as maintenance contractors • electricity and water costs increased by 5% to R3 338 million (US$193 million) in H1FY23 from R3 191 million (US$212 million) in H1FY22 mainly as a result of increased tariffs charged by Eskom Cash operating costs per kilogram increased by 11% to R740 944/kg (US$1 331/oz) from R667 812/kg (US$1 382/oz) in H1FY22. Derivatives and hedging The derivative programme stands at a net positive value of R503 million (US$30 million) as at 31 December 2022, mainly due to contracts locked in at favourable prices and additional exchange contracts being taken out during the current year at advantageous rates. In this reporting period, we recorded a net gain on derivatives of R313 million (US$18 million) compared to a net loss of R35 million (US$2 million) in H1FY22. This gain is a result of the favourable exchange rates compared to locked-in prices as well as additional exchange contracts being entered into at favourable positions. Revenue includes a hedging gain of R309 million (US$18 million) in H1FY23 compared to a gain of R143 million (US$10 million) in H1FY22 relating to the realised effective portion of hedge-accounted gold derivatives. Refer to notes 3 and 8 in the financial statements for details on the derivative programme. FY23 GROUP PRODUCTION, COST AND GRADE GUIDANCE FY23 production guidance for the South African operations remains unchanged at between 1 400 000 ounces to 1 500 000 ounces. FY23 AISC guidance also remains unchanged at less than R900 000/kg. Underground grade guidance remains unchanged at 5.45g/t to 5.60g/t. CHANGES TO THE BOARD Mr Andre Wilkens (non-executive director) and Mr Joaquim Chissano (independent non-executive director) retired as directors effective as of the conclusion of the 2022 annual general meeting on 29 November 2022. We would like to thank them for their contribution and service over the years. LOOKING AHEAD Harmony is transforming into a global gold-copper producer. However, our strategy of delivering safe, profitable ounces and improving margins through operational excellence and value-accretive acquisitions remains unchanged. The strong commodity prices have provided Harmony with good tailwinds as we manage the various exogenous challenges. Execution excellence and sustainable mining practices remain key to creating long-term value for all our stakeholders. Our shift into copper comes at a critical time for the global just energy transition. Higher quality gold reserves, near-term copper, alongside a growing international footprint will continue to de-risk Harmony. Our portfolio of gold and copper is positioned to provide shareholders with countercyclical diversification alongside improved margins. Sustainability is embedded in all we do and our culture encourages leadership excellence. Partnering with our various stakeholders and considering every aspect of E, S and G are part of our decision-making process, ensuring we conduct ethical and transparent mining practices at all times. True sustainability cannot be achieved by simply saying the right things. Creating positive change is about doing the right thing each and every day. This is what we do at Harmony. This is mining with purpose. Peter Steenkamp Chief executive officer

Reg. no. 1998/012055/21, VAT reg.no. 4950174682. INDEPENDENT AUDITOR’S REVIEW REPORT ON INTERIM FINANCIAL STATEMENTS To the Shareholders of Harmony Gold Mining Company Limited We have reviewed the condensed consolidated interim financial statements of Harmony Gold Mining Company Limited, set out on pages 12 to 31 in the accompanying interim report, which comprise the condensed consolidated balance sheet as at 31 December 2022 and the related condensed consolidated income statement, condensed consolidated statement of comprehensive income, condensed consolidated statement of changes in equity and condensed consolidated cash flow statement for the six- months then ended, and selected explanatory notes. Directors’ Responsibility for the Interim Financial Statements The directors are responsible for the preparation and presentation of these interim financial statements in accordance with the International Financial Reporting Standard, (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and the requirements of the Companies Act of South Africa, and for such internal control as the directors determine is necessary to enable the preparation of interim financial statements that are free from material misstatement, whether due to fraud or error. Auditor’s Responsibility Our responsibility is to express a conclusion on these interim financial statements. We conducted our review in accordance with International Standard on Review Engagements 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity. ISRE 2410 requires us to conclude whether anything has come to our attention that causes us to believe that the interim financial statements are not prepared in all material respects in accordance with the applicable financial reporting framework. This standard also requires us to comply with relevant ethical requirements. A review of interim financial statements in accordance with ISRE 2410 is a limited assurance engagement. We perform procedures, primarily consisting of making inquiries of management and others within the entity, as appropriate, and applying analytical procedures, and evaluate the evidence obtained. The procedures in a review are substantially less than and differ in nature from those performed in an audit conducted in accordance with International Standards on Auditing. Accordingly, we do not express an audit opinion on these interim financial statements. Conclusion Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed consolidated interim financial statements of Harmony Gold Mining Company Limited for the six months ended 31 December 2022 are not prepared, in all material respects, in accordance with the International Financial Reporting Standard, (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and the requirements of the Companies Act of South Africa. PricewaterhouseCoopers Inc. Director: Sizwe Masondo Registered Auditor Johannesburg 1 March 2023 The examination of controls over the maintenance and integrity of the Group’s website is beyond the scope of the review of the financial statements. Accordingly, we accept no responsibility for any changes that may have occurred to the condensed consolidated interim financial statements since they were initially presented on the website.

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 202216 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS FOR THE SIX MONTHS ENDED 31 DECEMBER 2022 (RAND) 1. ACCOUNTING POLICIES Basis of accounting The condensed consolidated financial statements for the interim reporting period ended 31 December 2022 have been prepared in accordance with International Accounting Standard (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee, Financial Reporting Pronouncements as issued by the Financial Reporting Standards Council, JSE Listings Requirements and in the manner required by the Companies Act no. 71 of 2008 of South Africa. The interim report does not include all the notes of the type normally included in an annual financial report. Accordingly, this report is to be read in conjunction with the annual report for the year ended 30 June 2022. The accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period. There were no new standards, amendments to standards or interpretations that became effective that had a material impact on the group's results or financial position. The condensed consolidated financial statements have been prepared to the nearest million and rounding may cause differences. During the six months ended 31 December 2022, the Tshepong Operations were reported on as two separate reportable segments, namely Tshepong North and Tshepong South, following the restructuring of the Tshepong Operations in the 2022 financial year. In accordance with the requirements of IFRS, the prior year comparative information has been re-presented in the segment report. The condensed consolidated financial statements have been prepared on a going concern basis. 2. IMPACT OF CHANGES IN GLOBAL OPERATING AND ECONOMIC ENVIRONMENT Covid-19 During the six months ended 31 December 2022, a significant increase in infections in China was experienced, with the subsequent discovery of new sub-variants of the Omicron strain. Although China has lifted the majority of its zero-covid policies, the impact continues to be felt, especially in supply chains around the world. Harmony is actively monitoring and managing the supply of critical items to ensure that production is not affected. In South Africa, although no new lockdown measures were reintroduced after the lifting of the national state of disaster in April 2022, the virus is still prevalent in normal day-to-day living. In Papua New Guinea, where the Hidden Valley operation is located, increases in positive cases have been experienced during the six months ended 31 December 2022, but no significant operational interruptions were experienced. Harmony is still in a position to manage Covid-19 as part of normal day-to-day activities and as a result management does not expect any further disruptions. Cost and inflationary pressures During the six months ended 31 December 2022, Harmony continued to experience heightened input costs driven by inflationary pressures. The effect has been especially pronounced on certain key items such as oil (directly affecting diesel supply and cost), electricity and certain chemical reagents used by treatment plans. Refer to note 4. The recent announcement by the energy regulator in South Africa, NERSA, of a 18% tariff hike in electricity will be incorporated into the 2023/2024 budgeting and forecasting process. This brings further impetus to Harmony's renewable energy programme. 3. REVENUE Six months ended Year ended Figures in million 31 December 2022 (Reviewed) 31 December 2021 (Reviewed) 30 June 2022 (Audited) Revenue from contracts with customers 22 761 21 537 41 677 Gold1 22 252 21 097 40 774 Silver2 428 347 663 Uranium2 81 93 240 Consideration from streaming contract3 189 271 471 Hedging gain/(loss)4 309 143 497 Total revenue5 23 259 21 951 42 645 1 Gold revenue has increased mainly due to the average spot gold price received which increased by 11.1% to R950 190/kg from R855 030/kg in December 2021. The increase was marginally offset by a decrease in gold sold from 24 674kg to 23 418kg, mainly due to the closure of Bambanani in June 2022. 2 Silver is derived from the Hidden Valley mine in Papua New Guinea. Uranium is derived from the Moab Khotsong operation. 3 Relates to the recognition of non-cash consideration recognised as part of revenue for the streaming arrangement. Refer to note 11 for further information. 4 Relates to the realised effective portion of the hedge-accounted gold derivatives. Refer to note 8 for further information. 5 A geographical analysis of revenue is provided in the segment report.

REVENUE continued The points of transfer of control are as follows: • Gold: South Africa (excluding streaming contract) Gold is delivered and certificate of sale is issued. • Gold and silver: Hidden Valley Metal is collected from Hidden Valley and a confirmation of collection is sent to and accepted by the customer. • Uranium Confirmation of transfer is issued. • Streaming contract Gold is delivered and credited into the Franco-Nevada designated gold account. 4.

Also contributing to the increase are annual and inflationary increases related to labour costs, consumables and services. The increase in production costs was offset by the closure of Bambanani on 30 June 2022. 2 The increase is attributable to the voluntary severance packages that were taken up following the closure of Bambanani and the restructuring of the Tshepong Operations. The bulk of the employees from these operations have been accommodated at other operations within the group. 3 The impairment assessment performed at 31 December 2022 did not result in any impairments or reversal at the operations that were tested. Refer to note 7. 5. TAXATION Current taxation The current taxation expense is higher for the six months ended 31 December 2022 mainly due to the non-mining tax related to the gains on foreign exchange derivative contracts and translation compared to the losses realised in the comparative period. The aforementioned changes were offset by the reduction in mining tax for Moab Khotsong, which was protected by the mining tax tunnel due to increased capital expenditure reducing taxable profit to below the 5% threshold. Due to the changes announced in the 2022 budget speech, the corporate tax rate applied to non-mining taxable income has been amended to 27% (2022: 28%) with the mining tax rate moving from 34% in 2022 to 33% for the current year. Further, the annual limitation of assessed loss utilisation to 80% of taxable income came into effect. Deferred taxation Deferred tax expense and liabilities The deferred tax expense for December 2022 is attributable to increased net taxable temporary differences primarily from the utilisation of the assessed losses and unredeemed capital expenditure in certain companies. Increases were also seen in the taxable temporary differences relating to property, plant and equipment of certain operating companies. The deferred tax expense for the December 2021 period was offset by credits relating to the creation of assessed losses and unredeemed capital expenditure in certain companies. As part of the Eva Copper transaction a R636 million deferred tax liability was recognised at 16 December 2022. Refer to note 12 for details of the transaction. Deferred tax asset As at 30 June 2022 a deferred tax asset continued to be recognised for both Harmony Company and Chemwes. Subsequently, the net deferred tax asset balance has decreased marginally in Harmony Company to R174 million (31 December 2021: R251 million, June 2022: R179 million), while Chemwes's net deferred tax asset has decreased to R4 million (December 2021: R55 million, June 2022: R24 million). A deferred tax asset continues to be recognised for both companies as it is probable that sufficient future taxable profits will be available against which the remaining deductible temporary differences existing at the reporting date can be utilised.

PROPERTY, PLANT AND EQUIPMENT Additions to property, plant and equipment Refer to note 12 and 13 for property, plant and equipment acquired and capital expenditure, respectively, during the six months ended 31 December 2022. Stripping activities and foreign exchange impact Costs capitalised related to stripping activities for the period ended 31 December 2022 amounts to R869 million with Hidden Valley accounting for R749 million of these costs. The foreign exchange translation movement on property, plant and equipment was an increase of R346 million for the six-month period. Impairment of property, plant and equipment At 31 December 2022, management performed an assessment for potential indicators of impairment of assets as well as potential indications for reversal of previously recorded impairment losses in terms of IAS 36 Impairment of Assets. Specific circumstances surrounding each of the individual cash generating units (CGUs) were considered in this assessment in order to identify significant changes in the six months since the last impairment assessment was performed. The Target, Kalgold and Kusasalethu CGUs experienced operational issues during the six months ended 31 December 2022. These operational issues were considered to be indications of potential impairment and therefore an impairment assessment was performed for these CGUs.

 
Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 202219 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS continued FOR THE SIX MONTHS ENDED 31 DECEMBER 2022 (RAND) 7. PROPERTY, PLANT AND EQUIPMENT continued Critical estimates and judgements The recoverable amount of mining assets is determined utilising real discounted future cash flows. The real post-tax discount rate used for CGUs tested for impairment ranged between 12.2% and 13% (June 2022: 12.3% and 13.1%) as at 31 December 2022. The gold prices applied to the life-of-mine plans of the CGUs tested for impairment are as follows: Six months ended Year ended 31 December 2022 (Reviewed) 31 December 2021 (Reviewed) 30 June 2022 (Audited) Rand gold price (R/kg) Year 1 956 000 880 000 931 000 Year 2 914 000 n/a 860 000 Year 3 855 000 n/a 816 000 Long term (Year 4 onwards) 825 000 n/a 763 000 The recoverable amounts of the CGUs were determined on a fair value less cost to sell basis. This is a fair value measurement classified as level 3. All key assumptions disclosed remained the same as at 30 June 2022 with the exception of gold prices and discount rates. Results of impairment and reversal assessment The impairment assessment performed at 31 December 2022 did not result in any impairments being recognised. The impairment of R144 million recognised for the six months ended 31 December 2021 related to Bambanani. The discount rate at that time was 12.59% and the short-term Rand gold price was R880 000/kg. Where CGUs had previously been impaired, management considered whether the impairment loss (or the contributors to the previously recognised impairment loss) no longer exists or might have decreased. Management considered general and specific factors for each CGU and concluded that although overall the gold price environment had improved from the time that the impairment losses had been recognised, the specific circumstances that led to the original impairments had not reversed. Furthermore, the service potential of the asset has not increased. Management therefore resolved it to be appropriate for no reversal of previously recognised impairment losses to be recorded for the six months ended 31 December 2022. One of the most significant assumptions that influence the life-of-mine plans and therefore impairment assessments is the expected commodity prices. Management determined that a reasonably possible change of 7.9% in gold prices, based on the standard deviation of market analysts' forecasted long-term gold price assumptions, would not have resulted in any impairments being recognised on the CGUs that were assessed at 31 December 2022.

BORROWINGS 9. TRADE AND OTHER RECEIVABLES The balance at 31 December 2022 increased by R650 million. This was mainly as a result of the VAT receivable increasing by R461 million and a R171 million increase in the gold debtor, both attributable to the timing of receipts. A further increase of R136 million relates to the prepayments balance, primarily due to the annual insurance payment in October 2022.

Refer to note 12. The new debt covenant tests for both the Rand and the US$ facilities are as follows: • The group's interest cover ratio shall be more than five times (EBITDA1/Total Interest paid) • Leverage2 shall not be more than 2.5 times. 1 Earnings before interest, taxes, depreciation and amortisation (EBITDA) as defined in the agreement also excludes unusual items such as impairment and restructuring cost. 2 Leverage is defined as total net debt to EBITDA. Loan covenants tests were performed for the loans for the period ended 31 December 2022 and no breaches were noted. For the December 2022 period, the group's interest cover ratio was 26.3 times (December 2021: 46.5 times) (June 2022: 43.4 times), while the group's leverage was 0.6 (December: 2021: 0.1) (June 2022: 0.1). Management believes that it is very likely that the covenant requirements will be met in the foreseeable future given the current earnings and interest levels, as well as the net debt position.

STREAMING ARRANGEMENTS continued 12. ACQUISITIONS AND BUSINESS COMBINATIONS ACQUISITION OF EVA COPPER On 6 October 2022, Harmony announced that it had entered into an agreement to acquire the entity which owns 100% of the Eva Copper project and a package of regional exploration tenements from Copper Mountain Mining Corporation (collectively Eva Copper). The acquisition is in line with the group's strategic objective of transitioning into a low-cost gold and copper mining company. Diversifying into copper enables Harmony to participate in the global transition to a low-carbon economy. The last condition precedent for the acquisition was fulfilled during December 2022, resulting in an acquisition date of 16 December 2022. Based on management's assessment, the transaction met the definition of a business combination as defined by IFRS 3 Business Combinations. This is based on the feasibility study, mine development plan and organised workforce acquired constituting substantive processes which significantly contributes to the ability to generate outputs. Management also opted to not apply the optional concentration test as per IFRS 3. The Eva Copper project was identified as a cash generating unit (CGU). Consideration transferred Consideration for the transaction amounted to a cash payment of R 2 996 million (US$170 million), paid during December 2022, and contingent consideration subject to the following criteria: • A maximum of US$30 million payable via a 10% sharing of net incremental revenue above US$3.80/Ib Cu (excess payment) • A maximum US$30 million payable on a new copper resource discovered and declared within the acquired tenements, calculated using a resource multiple of US$0.03/Ib Cu (new resource payment). These criteria are applicable for the entire life of the operation until the maximum payments are reached. As at 16 December 2022, the contingent consideration was valued at R169 million by using a probability weighted method for the new resource payment and a discounted cash flow valuation for the excess payment, both discounted at a post-tax nominal rate of 12.9%. All other assumptions applied in the valuation are consistent with those used in the valuation of identified assets acquired and liabilities assumed (refer below). The fair value calculated for the contingent consideration is level 3 in the fair value hierarchy due to the use of unobservable inputs. The remeasurement of the liability will be included in other operating expenses. The amount disclosed in the cash flow statement for cash paid for the acquisition of Eva Copper is equal to the cash consideration paid of R2 996 million. Acquisition-related costs The total of R214 million for acquisition-related costs for the six months ended 31 December 2022 relates to various costs directly attributable to the acquisition process. These costs include professional services fees and Australian stamp duty costs paid. Identifiable assets acquired and liabilities assumed The fair value exercise was prepared on a provisional basis in accordance with IFRS 3. Management is still in the process of gathering and assessing certain information and the impact thereof on the provisional fair values. No measurement period adjustments have been recognised for the six-month period ended 31 December 2022, based on the limited amount of time that has elapsed since the acquisition date. Streaming arrangement with Franco-Nevada Barbados continued The contract price receivable in US$/oz for each ounce of gold delivered during the period was as follows: • 1 July 2022 – 16 December 2022: US$442/oz • 17 December 2022 – 31 December 2022: US$446/oz.

Key assumptions for the level 3 fair value measurement of Eva Copper are the copper price, marketable discount rates, exchange rates and the feasibility study previously performed for the Eva Copper project. Mineral resource acquired which were not included in the discounted cash flows were valued using a copper resource multiple price of $0.03/lbs. The post-tax real discount rate used was 10.7%, the long-term A$/US$ exchange rate used was A$1.40/US$1 and a real long-term copper price of US$3.50/lbs was used. The valuation was performed as at 16 December 2022. The tax rates used to calculate deferred tax is based on Australian tax rates and tax laws that have been enacted at acquisition date. The deferred tax rate used as at 16 December 2022 was 30%. Fair value determination of acquired operations The provisional fair values as at the acquisition date are as follows: Figures in millions Total Non-current assets Property, plant and equipment 3 785 Current assets Restricted cash and investments 4 Trade and other receivables 12 Non-current liabilities Deferred tax liabilities (636) Provisional fair value of net identifiable assets acquired as at 16 December 2022 3 165 Since the provisional fair value of net identifiable assets acquired is within a reasonable range of the fair value of the consideration transferred, no gain on bargain purchase or goodwill is recognised for the transaction. Performance of acquired operation Immaterial costs were incurred for Eva Copper relating to the period ended 31 December 2022 and therefore no proforma information has been disclosed.

FINANCIAL RISK MANAGEMENT ACTIVITIES Foreign exchange risk Harmony's revenues are sensitive to the R/US$ exchange rate as all revenues are generated by gold sales denominated in US$. A weakening of the Rand will increase the reported revenue total; conversely a strengthening will decrease it. Harmony maintains a foreign currency derivative programme to manage foreign exchange risk. The limit currently set by the Board is 25% of the group's foreign exchange risk exposure for a period of 24 months. The audit and risk committee reviews the details of the programme quarterly. Refer to note 8 and the fair value determination section below for further detail on these contracts. The Rand weakened during the six months ended 31 December 2022, from R16.27/U$1 on 30 June 2022 to close at R17.00/US$1 on 31 December 2022 (31 December 2021: R15.99/US$1). Although the exchange rate weakened, there was a gain on the foreign exchange derivatives and forex contracts influenced by the average locked-in prices being higher than the exchange rate at 31 December 2022. The Rand's levels impacted negatively on the translation of the US$ debt facilities at 31 December 2022. Refer to note 10 for detail. Commodity price sensitivity The profitability of the group’s operations, and the cash flows generated by those operations, are mainly affected by changes in the market price of gold, and in the case of Hidden Valley, silver as well. Harmony enters into derivative contracts to manage the variability in cash flows from the group’s production, in order to create cash certainty and protect the group against lower commodity prices. The general limit for gold hedging currently set by the Board is 20% for a 24-month period. The limit set by the Board is 50% of silver exposure over a 24-month period. The audit and risk committee reviews the details of the programme quarterly. Refer to note 8 and the fair value determination section below for further detail on these contracts. An increase in the price of gold in US$ terms, together with the weakening of the Rand during both December periods, had a negative impact on the contracts that matured during the period as well as those that were outstanding at the reporting dates. Interest rate risk As high inflation continues to be prevalent in economies worldwide, central banks have maintained their policy of increasing interest rates. Harmony is affected by higher interest rates arising from both the US Federal Reserve and the South African Reserve Bank (SARB) increasing interest rates by 275 and 225 basis points, respectively. Although higher interest rates along with increased debt levels have had an unfavourable impact on the group's finance costs for the six months ended 31 December 2022, the group has not entered into interest rate swap agreements as the interest rate risk continues to be assessed as low. The audit and risk committee reviews the group's risk exposure quarterly. Credit risk Financial instruments which are subject to credit risk are restricted cash and investments, derivative financial instruments and cash and cash equivalents, all of which are invested with financial institutions that meet the group's policy requirements for credit quality, as well as trade and other receivables (excluding non-financial instruments). In assessing the creditworthiness of local institutions, management uses the national scale long-term ratings. The credit rating of the major South African (SA) banks has remained constant at AA+ for the period ended 31 December 2022 and 31 December 2021. The national scale investment grade rating of the banks remains high at AA+, and in line with the group's credit risk policy. An assessment of the expected credit losses (ECLs) for the financial assets measured at amortised cost for all reporting periods resulted in an immaterial amount for each instrument. The credit rating of the group's Australian counterparts remained at A+, yielding an immaterial ECL as well. Management will continue to review the underlying strength of the South African economy as well as the creditworthiness of the financial institutions and make any changes deemed necessary to safeguard the assets and reduce the credit risk. Capital risk management The consideration of R2 996 million for the acquisition of Eva Copper is the main contributor to the group's increased net debt compared to 30 June 2022. It remains the group's objective to adhere to a conservative approach to debt and maintain low levels of gearing. Net debt is as follows: At Figures in million 31 December 2022 (Reviewed) 30 June 2022 (Audited) 31 December 2021 (Reviewed) Cash and cash equivalents 2 195 2 448 2 940 Borrowings (6 905) (3 205) (3 552) Net debt (4 710) (757) (612)

FINANCIAL RISK MANAGEMENT ACTIVITIES continued (a) The majority of the balance relates to the equity investment in Rand Mutual Assurance. The fair value of the investment was estimated with reference to an independent valuation. A combination of the "Embedded Valuation" and "Net Asset Value" techniques were applied to revalue the investment at reporting dates. In evaluating the group's share of the business, common practice marketability and minority discounts as well as additional specific risk discounts were applied. There are no inputs to the valuation that a reasonably possible change would result in a material change in the fair value of the investment. (b) The majority of the level 2 valued assets are directly derived from the Top 40 index on the JSE, and are discounted at market interest rates. This relates to equity-linked deposits in the group's environmental rehabilitation trust funds. The level 1 valued assets comprise of listed equity securities designated as fair value through other comprehensive income instruments. The remaining balance of the environmental trust funds is carried at amortised cost and therefore not disclosed here. (c) The mark-to-market remeasurement of the derivative contracts was determined as follows: • Foreign exchange contracts comprise of zero cost collars and FECs: The zero cost collars were valued using a Black-Scholes valuation technique derived from spot Rand/US$ exchange rate inputs, implied volatilities on the Rand/US$ exchange rate, Rand/US$ inter-bank interest rates and discounted at a market interest rate (zero-coupon interest rate curve). The value of the FECs is derived from the forward Rand/US$ exchange rate and discounted at a market interest rate (zero-coupon interest rate curve). • Rand gold contracts (forward sale contracts): spot Rand/US$ exchange rate, Rand and dollar interest rates (forward points), spot US$ gold price, differential between the US interest rate and gold lease interest rate which is discounted at a market interest rate. • US$ gold contracts (forward sale contracts): spot US$ gold price, differential between the US interest rate and gold lease interest rate and discounted at a market interest rate. • Silver contracts (zero cost collars): a Black-Scholes valuation technique, derived from spot US$ silver price, strike price, implied volatilities, time to maturity and interest rates and discounted at a market interest rate. (d) At 31 December 2022, the fair value movement was calculated using a discounted cash flow model, taking into account forecasted dividend payments over the estimated repayment period of the loan at a rate of 11.5% (31 December 2021: 8.1%) (30 June 2022: 9.3%). A 21 basis point change (31 December 2021: 74 basis point change) (30 June 2022: 99 basis point change) in the discount rate, which would represent a reasonably possible change based on expected movements in lending rates, would not cause a material change in the fair value of the loan. The loan balance forms part of other non-current assets in the balance sheet. In the six-month period ended 31 December 2022, a repayment of R46 million was received. Refer to the cash flow statement. (e) Contingent consideration liabilities consist of the following: • Mponeng operation The consideration for the Mponeng operation and related assets included a contingent consideration determined using the expected gold production profile for Mponeng at a post-tax real rate of 10.11% (31 December 2021: 10.3%) (30 June 2022: 10.2%). Should the expected gold production profile increase by 7.6% or decrease by 7.6%, the contingent consideration liability would increase by R288 million (31 December 2021: R288 million at 7%) (30 June 2022: R251 million at 7.6%) or decrease by R218 million (31 December 2021: R208 million at 7%) (30 June 2022: R189 million at 7.6%), respectively. This represents reasonably expected changes which were determined based on the standard deviation of previous years' production of the Mponeng operation. No other reasonable expected changes in key unobservable inputs would have caused a material change in the fair value of the liability. Fair value determination The fair value levels of hierarchy are as follows: Level 1: Quoted prices (unadjusted) in active markets Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset, either directly (that is, as prices) or indirectly (that is, derived from other prices) Level 3: Inputs for the asset that are not based on observable market data (that is, unobservable inputs).

Refer to note 12 for further information. There are no inputs to the valuation that a reasonably possible change would result in a material change in the fair value of the liability. The carrying values (less any impairment allowance) of short-term financial instruments are assumed to approximate their fair values. This includes restricted cash and investments carried at amortised cost. The fair values of borrowings are not materially different to their carrying amounts since the interest payable on those borrowings is at floating interest rates.
